Research ArticleOpen accessIn the abstractExperimental Investigation of Limonene-based Environmental-Friendly Emulsion Drilling MudOlaitan Oluwaseum Micheal, Orodu Oyinkepreye David, Ehinmowo Adegboyega BoluThe use of emulsion drilling mud in the oil and gas industry has gained wide acceptance. However, the disposal of drill cuttings and the waste of such emulsion drilling mud usually poses environmental concern. Hence, there is the need to seek oil from biodegradable sources as an alternative to the current conventional diesel oil which constitute environmental threat. In this … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 12 Jun 2017 · 7,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Chemical Properties on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to investigate the seriousness of degradation of peat swamp forest caused by skidding system in terms of its function as a carbon sink. In this study, we formulated assumptions that conditions of our research site before the introduction of skidding system were in their natural states, thus that changes measured are clearly caused by skidding … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,915 accessesView PDFCite
Research ArticleOpen accessIn the abstractAgricultural Resources Allocation and Field Crops CompetitionElgilany Ahmed, Jamalludin Sulaiman, Saidatulakmal MohdProblem statement: Field crops are considered as essential cash and food crops produced in River Nile State (RNS) of North Sudan include cereal, food-legumes, vegetables and fodders beside the perennial crops. They are the main source of household income and regarded as a major part of the daily diet for the Sudanese. In other words they play an important role … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 7,979 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of a New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part II: Optimization of the System for Escherichia coliEric Carnes, Ebtisam WilkinsThe optimization of a flow-through immunoassay system was conducted to achieve rapid detection of low concentrations of E. coli bacteria. The system includes a new immunosensor that uses newly developed, disposable immunofiltration membranes to yield a system that is sensitive as well as simple. Comparison of the performance of this system with conventional immunoassays demonstrated a significantly shorter time for … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating Rapid Thermoform Tooling Via Additive Manufacturing (3d Printing)Gene Haeberle, Salil DesaiAdditive Manufacturing (AM) has matured from a prototyping tool to a soft production tooling in recent years. This research elaborates the role of AM technology (3D printing) in the design, prototyping and development of a rapid thermoform tooling. The Fused Deposition Modeling (FDM) 3D printer was implemented to fabricate thermoform tooling in Polypropylene Styrofoam (PPSF). We contrast the additively manufactured … …American Journal of Applied Sciences, Vol. 16, Issue 8 · 9 Oct 2019 · 9,410 accessesView PDFCite
Research ArticleOpen accessIn the abstractPYROLYSIS OF EMPTY FRUIT BUNCHES: INFLUENCE OF TEMPERATURE ON THE YIELDS AND COMPOSITION OF GASEOUS PRODUCTMohamad Azri Sukiran, Loh Soh Kheang, Nasrin Abu Bakar, Choo Yuen MayWith the increasing concern on fossil fuel depletion and environmental problems, the utilization of renewable biomass resources is expected to play an important role in the future. Biomass can be converted into a variety of fuels and chemicals by different processes; one of which is pyrolysis that has been subjected to extensive research in recent years. In this study, pyrolysis … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 3 Feb 2014 · 7,616 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrowave Assisted Bioethanol Production from Sago Starch by Co-Culturing of Ragi Tapai and Saccharomyces CerevisiaeN. Saifuddin, Refal HussainProblem statement: Environmental issues such as global warming and recent events throughout the world, including the shortage of petroleum crude oil, the sharp increase in the cost of oil and the political instability of some crude oil producing countries, have demonstrated the vulnerability of the present sources for liquid fuel. These situations have created great demand for ethanol from fermentation … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoybean Response to 1-Aminocyclopropane-1-Carboxylate Deaminase-Producing Pseudomonas under Field Soil ConditionsEdi Husen, Aris Tri Wahyudi, Antonius Suwanto, GiyantoProblem Statement: 1-Aminocyclopropane-1-Carboxylate (ACC) deaminase-producing bacteria have been known to promote plant growth by decreasing ethylene inhibition of various plant processes. However, their efficacy under field soil conditions may vary depending on the range and variability of the environmental factors. This study examined the ability of eight promising isolates of ACC deaminase-producing Pseudomonas to enhance soybean growth under acidic and … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 24 Jun 2011 · 8,250 accessesView PDFCite
